I applied through university. The process took 1 week. I interviewed at China Poly Group (Hong Kong) in Oct 2014
Interview
Filled out the form, got an email for an interview. Showed up and waited for a while for the HR to come in. Standard interview questions in a group of around 8, you're allowed to speak either Mandarin or English. I do not think you need experience in this one. Pretty chill.
